Valid vs. Sound or the difference between Logic and Ethics

Valid vs. Sound or the difference between Logic and Ethics

The concept of a “valid” argument is that IF all the premises are true, then the conclusion MUST be true.

A “sound” argument is a valid argument that HAS true premises.

It seems to me that the sign above is a valid argument, If A, then B. If B, then C — therefore if A then C — BUT, I do question the truth of the premisies —

So, this sign moves us from logic to Intro to philosophy and/or Ethics, because the truth of the premises is the sort of question we tackle there.
